With atomic mode setting in the kernel, I think you're probably right in proposing to eliminate explicit CRTC allocation from that. I do think you'll want to indicate the number of available CRTCs in the display engine, and the number of CRTCs each monitor consumes. Do you know if there are some of these monitors that can display lower resolution modes with only a single CRTC? Or is the hardware so separate that you end up always using multiple CRTCs to drive them?
The one I tried definitely can; indeed it has to because the VBIOS doesn't know how to set up MST and drives the port in DP 1.1 mode. I'm sure someone will build a monitor that only turns on half of the display if you do that, but I'd be kind of surprised if someone made one that just doesn't work if you use a DP 1.1-only GPU.
